Adaptive Precoding for Downstream Crosstalk Precancelation in DSL Systems Using Sign-Error Feedback
Abstract
The performance of many very high bit rate digitalsubscriber line (VDSL) systems is limited by the effects of crosstalkamong the wires in a bundle. For the downstream, a precoder cancompensate for this, provided that some crosstalk channel informationis available at the transmitter. In this paper, we investigatethe issue of precoder design based on a particular type of feedback:it is assumed that each receiver sends back the (c ....etc

ABSTRACT

An expert system for personal computer troubleshooting, developed as part of MCA 6th semester Course project work, National Institute of Technology, Calicut, is presented. It is implemented on a personal computer. The proposed system includes many characteristics of an expert system because it can be expanded easily by adding new information to its knowledge base or by changing its existing information. The basic idea behind this expert system is to provide a non-expert with the necessary information and interaction ....etc

Abstract:
The keys to successful motor operation include a total understanding of the application, then choosing the proper type of motor for the application. This must then be followed by the proper installation – mounting, coupling, and a total understanding of the motor surroundings or environment. Of course, for continued success proper maintenance of the motor must also be performed. Many problems could be avoided if the application and environment were understood, while others may be caused by a changin ....etc

Digitally Modulated Carrier Amplitude



•When measuring the amplitude of a digitally modulated carrier, make certain you are measuring its average power level

•Use test equipment that performs automated measurements, rather than trying to make error-prone manual measurements that require bandwidth, IF filter, log amplifier and detection corrections
